Hi everyone.

I have just started with programming in C++ a few weeks ago so I have not that much understanding of it. I have been given a project of making a Sudoku game,

I have got my code to randomly choose a number and check it against the other numbers in the same row and column but i can't get it to check against the other numbers in the subgrid.

Heres the main part of my code
Code: CPP
`int bad;int x;int i1;int j1;int i;int j;int n [ROWS][COLS];    for (i = 0; i < ROWS; i++) {        for (j = 0; j < COLS; j++) {        do { x = rand()%9 +1; bad = 0;   // random number                        for (i1 = 0; i1 < i; i1++)           // Checking against other numbers in the row            if (x == n[i1][j]) bad = 1;        for (j1 = 0; j1 < j; j1++)       // Checking against other numbers in the column                if (x == n[i][j1]) bad = 1;                }while (bad);        n[i][j] = x; }    }    cout << "Sukodu Board:\n";    for (i = 0; i < ROWS; i++) {        for (j = 0; j < COLS; j++)            cout << n[i][j] << " ";  // Prints out the numbers  `
I hope that you can follow the code.

Thanks
